The Long Loneliness is the autobiography of Dorothy Day, published in 1952 by Harper & Brothers. In the book, Day chronicles her involvement in socialist groups along with her eventual conversion to Catholicism in 1927, and the beginning of her newspaper the Catholic Worker in 1933.[1][2]
It has been characterized as "a remarkably candid account, without piety, of her journey to faith".[1] A 1952 review in The New York Times focused on her interactions with communism and her journey away from it while staying true to her radical roots: "This book will not shock anybody. It may touch many, whatever their secular or religious faith, who lament the kindliness and sympathy that Communists found among certain left-wing groups -- and betrayed."[2]
